Abstract

본 발명은 높은 스티브니스(stiffness)를 갖는 폴리프로필렌의 제조방법에 관한 것으로, 먼저(A) 주기울표 IV B족의 전이금속화합물, (B) 알루미노옥산 및 (C) 물로 형성된 메탈로센계 지글러-나타 올레핀 중합 촉매를 이용하여 시클로펜텐 고분자를 합성하고, 이를 폴리프로필렌 중량당 0.2에서 1,000중량ppm의 양으로 폴리프로필렌에 혼합하여 제조함을 특징으로 한다.The present invention relates to a method for producing polypropylene having a high stiffness. It is characterized in that the cyclopentene polymer is synthesized by using a olefin polymerization catalyst and mixed with polypropylene in an amount of 0.2 to 1,000 ppm by weight per polypropylene.
